1 .tioned co-pending application.

Before explaining in detail the present invention, it is to beunderstood that the invention is not limited in its application to thedetails of construction and arrangement of parts illustrated in theaccompanying drawing, since the invention is capable of otherembodiments and of being practiced or carried out in various ways. Alsoit is to be understood that the phraseology or terminology employedherein is for the purpose of description and not of limitation, and itis not intended to limit the invention beyond the terms of the severalclaims hereto appended as considered in view of the prior art and therequirements thereof.

, The invention will be more clearly understood from the followingdescription in conjunction with the accompanying drawing in which:

Fig. 1 is a plan view of a chase showing a type locked therein by quoinsembodying the inveng tion.

Fig. 2 is a perspective view of ing the invention.

Fig. 3 is a perspective view of a portion of the quoin. Figs. 4 and 5are sectional views taken upon the line 4-4 of Fig. 2 showing the partsof the quoin in different positions, and

Fig. 6 is a sectional view of the quoin taken upon the line 6-6 of Fig.2.

The quoin illustrated in the accompanying drawing comprises a hollowcasing 10 made up of two cooperating open box-like parts 11 and 12.

A portion of the ends of the parts 11 and 12 are cut away as indicatedat 13 and pins 14 are secured in the cut away end portions. The pins 14I at each end are adapted to be connected by a spring 15. Each of thelongitudinal side walls 16 of the part 12 is provided with a projection17 intermediate its ends adapted to be received in a depression 18formed intermediate the ends of a quoin embodyeach of the longitudinalside walls 19 of the part 11. One of the projections 17 is provided withan elongated slot 20. Each of the side walls 19 of the part 11 are alsoprovided with a projection 23 having a slot 24 serving as a guide forthe shaft 21 carrying a pinion 22.

A pair of cooperating wedge members 25 are positioned within the casing10 and one is adapted to slidably engage the interior surface of theouter wall 26 of each of the parts 11 and 12 of the casing. Each of thewedge members 25, preferably, is constructed in the form of a channelstamping, the web of which is arranged to engage the interior surface ofone of the walls 26. A portion 29 of the edge of each of the legs 27 ofthe channel is inclined and provided with rack teeth 28 adapted toengage the pinion 22. Another portion of each of the legs 27 of thechannel is provided with a projection 30, the outer edge of which isinclined and adapted to engage the inclined portion 29 of one of thelegs of the other channel.

The type 31 is positioned in a suitable manner between the frame membersof a chase 32. The spaces between the edges of the type and frame of thecasing are built up by blocks of wood 33 or the like. The quoin is thenpositioned in the spaces between the blocks 33 and the frame and theshaft 21 is rotated to rotate the pinion 22 by inserting a tool throughthe slot 20 to engage a socket in the end of the shaft 21 to cause themembers 25 to move longitudinally in opposite directions, therebyvarying the distances between the corresponding outer parallel walls 26of the parts 11 and 12 of the casing. The longitudinally spaceprojections 30 bearing at all times upon the inclined edge portions 29effectively prevent tilting of the quoin. The pinion efiectively locksthe wedge members 25 in their adjusted position.

We claim:

1. A quoin comprising a casing having two separate parts of channelcross section movable laterally in one direction, the side walls of oneof the casing parts each having an intermediate recessed portion, theside walls of the other of the casing parts each having an intermediatecorresponding outer parallel surfaces and inner inclined surfaces havingteeth, each of said bars having a projection extending toward the otherbar and adapted to engage the inclined surface thereof, at least one ofsaid recessed portions and one of said projections having an opening,and

a pinion adapted to engage said teeth and having an opening of polygonalshape adapted to be engaged by a key inserted through the openings insaid projection and recessed portion, the opening in said recessedportion serving as a bearing the adjacent side walls on one side of thecasing being provided with alined openings, and a pinion adapted toengage said teeth and having an opening of polygonal shape adapted to beengaged by a key inserted through said openings in the casing, one ofsaid openings serving as a bearing preventing lateral movement of theaxis of the pinion longitudinally of the quoin.
